Foody is a polyester staple fibre manufacturer(Es fiber manufacturer ) and focuses on the production of ES Composite Staple Fiber (PE/PET), mainly used for Hot Air Nonwoven Surface/Bottom layer, Diversion layer, Acquisition Distribution layer(ADL) and other uses;  This terminal is suitable for baby diapers, sanitary napkins, adult pee pads, napkin, bath towel, disposable tablecloth, composite core and other sanitary materials.

Mothers often touch and knead diapers with their hands when buying diapers.

They may not know that what they are touching is the top layer of the diaper.

Diapers are mainly composed of three parts: the surface layer, the absorbent core and the bottom layer. The surface layer is responsible for receiving urine and infiltrating it. The fluff pulp and SAP in the core are responsible for absorbing urine, and the bottom layer is responsible for leak prevention. Sexuality also plays an important role.

The main function of the surface layer is to quickly transfer the liquid to the next layer (core absorbent layer), emphasizing on drainage, penetration, etc. On the other hand, since the surface layer is the part that directly contacts the baby's PP, the surface layer needs to be maintained Dry and skin-friendly. Combining the above characteristics, most of the surface materials in the domestic market are non-woven fabrics, especially air-through non-woven fabrics and spunbond non-woven fabrics.

Hot air non-woven fabric

Hot-air non-woven fabric, as the name suggests, is a non-woven fabric made of fibers heated and reinforced by hot air. It is mainly used for surface layers, bottom films, and flow-guiding layers.

Hot air non-woven fabric has the following characteristics:

1. The space structure is relatively three-dimensional, and the resilience is good, and it can temporarily store liquids more than 10 times its own weight;

2. There are many pores, the density is small, the structure is loose, and the time for liquid penetration is short;

3. If the fiber direction is adjusted, liquid diversion can be performed.

Therefore, the hot air non-woven fabric has the characteristics of high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air permeability and water permeability.

Among the air-through non-woven fabrics, there are two-layer composites. This kind of surface layer has a large thickness and strong coverage, which can make the diapers more delicate and clean, and it looks more high-end. The price of cloth will be higher, so it will be mostly used in high-end diaper products.

Air-through nonwovens include ES air-through nonwovens, 3D air-through nonwovens, PET/PE air-through nonwovens, PP/PE air-through nonwovens, etc. The thickness, bulkiness, softness, etc. are different, and the prices are also different. There are different types, but the most commonly used one on the market is single-layer ordinary air-through non-woven fabric.
